Problems solved by technology

If the shutdown time is too long, the above system operations cannot be carried out normally, which will have a great impact on the company's production, especially for the fast-paced continuous casting and rolling production process, which may seriously cause production shutdown
System upgrades will not be possible without significantly reducing production system downtime

Embodiment Construction

[0022] figure 1 The system upgrade method according to the present invention is illustrated by taking the upgrade of the SAP ERP system as an example. The system upgrade method uses two servers. The ERP system first runs on the first server. When the ERP system on the first server is running, the ERP system is upgraded on the second server. Then import the data generated when the ERP system on the first server is running to the upgraded ERP system on the second server. Along with that, operate with the upgraded ERP system on the second server. It should be clear that the system upgrade in the present invention includes not only system upgrade in the traditional sense but also other operations that require long downtime such as system maintenance and database reorganization.

[0023] Below, combine figure 1 The system upgrading method according to the present invention is described in detail. exist figure 1 In the shown embodiment, the first server is the current server,...

Abstract

The invention provides a system upgrading method. The method comprises the steps of synchronizing a first system positioned on a first server and a second system positioned on a second server, upgrading the second system on the second server when the first system on the first server runs, importing a part of data produced by the first system synchronized during running into the second system when the first system runs, importing other parts of data produced by the first system synchronized during running into the second system after the running of the first system is stopped, and running the upgraded second system. The skillful combination of upgrading technology, system migration technology and business order follow-up technology is realized according to the system upgrading method, system upgrading and business operating do not influence each other, the downtime of a production system can be greatly reduced, and the influence on business production caused by machine halt is minimized.

Description

technical field [0001] The invention relates to a method for upgrading a system, in particular to a method for upgrading an enterprise resource planning system in the metallurgical industry. Background technique [0002] The SAP system (Systems Applications and Products in Data Processing) is an open and integrated enterprise resource planning (Enterprise Resource Planning, hereinafter referred to as: ERP) system based on the client / server structure. The SAP ERP system of the large-scale manufacturing industry is a three-level (Manufacturing Execution System (Manufacturing Execution System, MES for short)) and four-level (ERP) tightly coupled system that integrates smelting, hot rolling, and cold rolling large-scale 7X24-hour continuous production. Operations from raw materials entering the factory, production feeding, receiving, inspection result recording, quality judgment, allocation, to finished product delivery are all carried out in the third and fourth level systems i...
